To all whom t muy concern.- f

Be it known that I, HERMANN MERKEL, a citizen of the United States, residing at the cityof St. Louis, in the State of Missouri, have invented certainnew and. useful Improve ments in 'Incandescent Vapor-Burners, of which the following is a'i'ull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specitication. A y 'A f My invention relates toa burner for vaporizin g hydrocarbon oils and burning the Vapor within a gauze mantle to produce an incandescent or white flame for illuminating purposes.

Myinvent-ion consists in features ot' novelty hereinafierfully described,and pointed out in the claims.

Figure I is a side elevation ot my burner with parts lshown in vertical section. Fig. 1I is an enlarged vertical sectional View of the burner.vv Fig.III is across-sectional view taken on the line lII III, Fig. II. Fig. IV is a crosssectional view taken on the line IV'IV, Fig. II, looking downward.

1 designates the supply-pipe, to which a coupling 2, that supports the burner, is applied. The coupling 2 is provided with an aperture 3,providing communication from the su pply-pi pe, said aperture being cont-rolled by a valve 4, the inner end of which is adapted to bemoved into or outof the said aperture.

5 designates a conveying-pipe connected to the coupling 2. This pipe contains a filling 6, of asbestos or other suitable material, through which the hydrocarbon oil may low, the lling being designed to control the flow of 'the v oil for the purpose of maintaining a uniform supply to the burner, so as to avoid pulsation in the operation of the burner.

On the upper end of the conveying-pipe 5 is a jet-tube 7, that contains a jet-orifice S, through which generated vapor passes from the pipe 5 into the burner.

9 designates a heat-conductor supported on the jet-tube 7, which is of open form at its lowermost portion and extends upwardly to its cylindrical hollowportion 10. This heatconductor is designed` to transmit the heat from the burning vapor consumed at its npper end down to the jet-tube 7 for the purpose of vaporizing the-hydrocarbon oil before -it reaches the jet-orifice S.

- In the upper cylindrical end of the heat- Y conductor 9 is a gauze distributing-cap 11, through which the vapor passes to be consumed. In the center of this distributingcap is aspreader 12, that serves to prevent the direct upward How of the vapor as it passes through the distributing-cap and causes it tol be directed in outward or diverging directions in its passage through said cap.

13 designates an air and vapor mixing tube containing apertures 14, through which air may enter into said tube to combine with the vapor as it is admitted into saidtube from the jet-orilice S. trolled by a regulating-sleeve 15, containing Y apertures 15, adapted io register with the apertures 14, so as to regulate'they admission of air to the desired extent into-the air and gas mixing tuhe 13. The regulator-sleeve-15` is provided withan annular dome-shaped turn-piece 16, which maybe grasped by the fingers to turn the sleevey on the mixing-tube 13,130 cause thedesired registering or partial registering of the apertures in the mixingtube and regulator-sleeve. The interior of the cylindrical portion 10 of the heat-conductor also providesfor the mixingof the air and gas before they reach the distributing-cap 11,

. and for the purpose of regulating the size of the mixing-chamber I provide a flaring collar 17, surrounding the upper end of the tube 13, this collarrbeing Amovably vmounted'on said tube, so that it may be slipped np and down thereon for the purpose of increasing ordiminishing the extent of the mixing-chamber above the'tuoe 13. v

18 designates a gauze mantle supported above the main portion of the burner and having its lower open end inclosing the dis` tributing-,cap 11 ot' the burner, so that the discharge through said cap is directed to the interior of said mantle.

I have shown a chimney-supporting frame 19, which may or may not be used in connection with the burner, as it is not essential to the burner operation.

In the use of this burner the initial vapori'- zation o'f the hydrocarbon oil is accomplished by applying for a short period heat to the con- "The apertures 14 are con- Veying-pipe 5 or jet-tube 7, after which the created vapor is ignited to burn Within the mantle 18 as it passes through the distributing-cap 1l. The heat from the consumption of the vapor causes the heating of the upper end l0 of the heat-conductor 9, and as this heat-conductor becomes hot at its upper end the heat travels downwardly throughout its extent and reaches its connection with the j et-tube 7, the said jet-tube becoming heated,

whereby the oil Within said tube is superheated and vaporized and vaporization is continued Within said jet-tube throughout the operation of the burner. For the purpose of causing a more effective heating of the heatconductor I provide slits l0 in its upper end, through which small jets of flame may pass and thereby cause an acceleration in the heating process of the said heat-conductor.

'l/Vhile I have shown and described this burner as used lfor burning hydrocarbon oils, it is evident that it may be used for burning gases, and I therefore do not limit myself to its use as a vapor-burner.

The spreader 12 is provided with a stem 2, projecting above the top of the distributing-cap.

I claim as my invention l. In a burner, the combination-of a conducting-pipe, a jet-tube, a heat-conductor having communication with said jet-tube, said heat-conductor being provided with a cylindrical upper end, a distributing-cap located in the upper end of said heat-conductor, and a gauze lnantle surmounting said distributing-cap, and surrounding the upper end of said heat-conductor; substantially as set forth.

2. In a burner,'the combination of a conveying-pipe containing a porous filling, a jettube mounted on said conveying-pipe, a heatconductor mounted on said jet-tube,said heatconductor having a cylindrical upper end provided With slits, a distributing-cap mounted in the upper end of said heat-conductor, and

a gauze mantle surmounting said distributing cap, and surrounding the Lipper end of said heat-conductor; substantially as set forth.

3. In a burner, the combination of a conveying-pipe, a jet-tube mounted on said conveying-pipe, an apertured mixing-tube surmounting said jet-tube, an apertured regulating-sleeve surmounting said mixing-tube, a flaring collar on the upper end of said mixingtube, a heat-conductor supported on said jettube and having cylindrical upper end, a distributing-cap in the upper end of said heatconductor,a spreaderin said distributing-cap, and a gauze mantle surmounting said distributing-cap, and su rro undin g the upper end of said heat-conductor; substantially as set forth. v

4. A Vapor-burner comprising a conveyingpipe adapted to contain a filling of oil-controlling material, a jet-tubehaving a jet-ori'- fice and secured to the conveying-pipe, an open heat-conductor having a longitudinallyslitted cylindrical portion and seated on the jet-tube, the gauze distributing-cap located in the upper end of the cylindrical portion, the mixing-tube having apertures, surrounding the jet-tube and extending into the cy-A lindrical portion, the vertically-movable upwardly-flaring collail mounted on the mixingtube, and the regulating-sleeve having apertures and a dome-shaped turn-piece and surrounding the mixing-tube; substantially as described.
